Hey.
We are a group that are playing vanilla Descent, and we played around 10 times and so far they never killed the boss in any of the adventures. I thought it was because it they needed time to get used to the game and learn the rules and figure out the game mechanics. But it seems we never get to kill the boss since they usually never get over the armor-value of the boss even with gold-treasures. My group dropped the idea to try and play it anymore because the high difficulty. What are we doing wrong?
